When you are in charge of hosting a convention you have to make sure of several things like having the list of who will be attending, how many will they be and what food will they eat (it actually depends on the time). A convention is not as interesting if you do not have a good sound system. With poor sound system, the attendees will only tend to be sleepy especially if there is much talk to be listened to. A wonderful nady audio may do the trick but make sure you have several breaks of entertainment in between talks to get more attention.
